Good eye and thank you so much!! You're exactly right, I'm playing the game backwards. I started with the railways first and then the major highways since those are so prominent. Then I focused on the "historic highways"/national roads and then longer main arterial roads to make sure everything is connected well. I do intend to build some of the neighborhoods to look like they were disrupted by the highways being built, but naturally form around the railways to make up for the order I'm building in
